Post Some Problems

Ok first i'll list all the mods before telling anyone the problem the block is a 62 327 coverted to HEI ignition slight build up on cam and stock heads with 1.94 1.60 valves and i'm running a 600 electric choke edelbrock carb and a performer dual plane edelbrock intake.
I think that covers the mods also a 350turbo tranny with a 2300 stall and posi 3.73 gears in the rear.
Ok now for the problem it idels fine and even gets up ok for the first few seconds but as soon as i get on it, it wants to hesitates and wont go any faster at first i though it was the carb so i worked with every thing on the edelbrock carb. Then it still did it at any settings on the carb so I swaped out the edelbrock for a 750 Holly and it did the same thing with that carb as it did with the edelbrock at any settings my fuel pump is rated at 8psi I'm not sure if this has anything to do with it.
Also I checked the timing and as far as I can tell its on. I've been told to check out the rockers to make sure they aren't too tight or maybe it has to do with the ignition system.

Any help would be very appreciated.
Thanks in advance.

When you say, "if gets up fine" are you stabbing it from a dead stop? Does it run well, except for the fact that it's doggy? Is this a new engine? What are your camshaft specs? Where do you have your timing set at? Do you have any idea of what kind of advance curve your distributor has? It's hard to tell what is happening to your car without more detailed information. If you don't have this puppy seriously ovecammed, it should be pretty snappy with 3.73 gears, so you need to check compression, start over with all of the basics.

Good advice from Nairb, always start with the basics.

Then try raising the float level and see if it gets better or worse. If it does, it is fuel related. If not then I would look at your distributor and start determining if is advancing fast enough. When an engine is modified it's timing requirements charge drastically and it can actually perform worse than stock until you dial all the components in together.

Do some tests and let us know what you find.
  • Initial timing, total crankshaft timing, and rpm it is "all in" by.
  • Examine the plugs and note colour and look for little aluminum balls on the insulator for signs of detonation.
  • "The basics", compression, vacuum at idle, fuel pressure at the carb, float height, etc. etc.

Let us know what you find and look for vacuum leaks, they can cause your problem.
